这可能是一个愚蠢的问题，但是当我尝试在 databricks 中进行 pivit 时如何设置spark.sql.pivotMaxValues？我遇到了这个巨大的错误，org.apache.spark.sql.AnalysisException: The pivot column census_block_group has more than 10000 distinct values, this could indicate an error. If this was intended, set spark.sql.pivotMaxValues to at least the number of distinct values of the pivot column.; 所以有人知道我该如何解决这个问题吗？
import org.apache.spark.sql.SQLContext
val df = censusBlocks.toDF
df.groupBy("B08007e1").pivot("census_block_group").sum("B08008e4")
df.show()
